How The Witcher 4 Tech Demo Used Unreal’s Animation Framework
Watch a recorded Unreal Fest Orlando 2025 session that unpacks how Unreal’s Animation Framework powered The Witcher 4 UE5 tech demo. You’ll get practical insights into AAA animation workflows, tool integration, and production decisions in UE5.6. A must-watch for teams scaling character animation and aiming for next-gen fidelity in Unreal Engine.
Inside AC Shadows’ RTGI: Probes, Ray Tracing, and Denoising at Scale
Assassin’s Creed Shadows ships ray-traced diffuse and specular GI across a massive, dynamic world with a hybrid pipeline: per-pixel ray tracing plus a cascaded probe radiance cache. The team details screen-space remarching, a coarse BVH, SH-encoded lighting, and multi-pass denoising to control noise. They tackle translucency, thin walls, and dense vegetation with secondary shadow maps, alpha-test approximations, probe AO, and GTAO. Candid performance figures, limitations, and a roadmap reveal how they balance quality, stability, and scalability.

Why Games Love Paging: A Deep Dive into Virtual Memory
This deep dive explains how OSes keep large programs responsive using paging, virtual memory, and demand loading. It moves from the limits of contiguous allocation to page tables, page sharing, and handling page faults—framed with an open-world game analogy. You’ll also learn stack vs heap mechanics, how malloc/brk/sbrk work, and why mmap (file and anonymous) matters on Linux. Essential context for asset streaming, allocator design, and memory tuning.
Stop Singleton Sprawl: Unity Dependency Injection with VContainer
Singletons are fine—until live ops and A/B tests turn your reward flow into if-else spaghetti. This video shows how constructor injection and VContainer make dependencies explicit, improve testability, and let you swap implementations per cohort. You’ll see practical bindings, singletons, entry points, and MonoBehaviour method injection. Build flexible systems that scale without rewrites.

From Showrooms to Verification Spaces: CGI + GenAI for Trust at Scale
In this Unreal Fest session, Porsche’s MHP unveils how its Elastic Content Platform blends CGI and GenAI in Unreal Engine to make authenticity a measurable growth driver. With showrooms becoming “verification spaces,” the talk shows how to operationalize trust at scale so customers stop questioning what’s real. See how photoreal, interactive content converts confidence into revenue across automotive experiences.
Master Steam Tags: Beat “More Like This” with Data-Driven Picks
Boost your Steam discoverability with a data-first tagging strategy. Analyze 10–20 similar, moderately successful games, then prioritize their most relevant tags—start with core genres and unique features. Keep to ~15 tags, order them carefully (the first five matter most), and use SteamDB to validate popularity and fit. Revisit your tags before major beats and every 3–6 months to stay aligned with your audience.
